What is the diffusion of light?
The diffusion of light is the process by which light spreads out from its source. The light energy is transferred through photons, which are particles of light that travel in straight lines until they hit an obstacle or object. When the light hits an object, it can be either absorbed, reflected, or scattered by the refracted. The amount of refraction that occurs depends on the material's properties and the angle of incidence. Some materials are able to refract light more than others, and some materials can even be transparent or opaque. For example, water is able to refract light more than air, which is why we can see things underwater.
